Coding resistance

If you replace the PCB, you must remove the
front left coding resistor (
1
) (plug X24) on the
old PCB and insert it into the new PCB.
If you are replacing only one of the two components (PCB
or display), the parameter matching functions automati-
cally. By switching on the boiler, the new component takes
over the previously set parameters from the unreplaced
component.

firm with OK.
